To motivate my analysis, I document a positive cross-country correlation between intergenerational persistence of income (and education) and educational assortative mating. I then develop an overlapping generations model in which parents invest in their children's education and individuals choose whom they are going to marry, and estimate the model to fit the postwar U.S. data. My results suggest that both of these changes have affected the intergenerational earnings persistence, but that the marriage decision plays only a very small role in these results.

As economias de aglomeração apresentam externalidades que impactam sobre os vetores de preços da economia. As interações que ocorrem nas aglomerações são relevantes para a compreensão dos benefícios gerados pela proximidade. Tais benefícios impactam diretamente o salário do trabalho e os preços dos imóveis, entre outros. Muitos trabalhos focaram em estudar economias de aglomeração no contexto espacial agregado, mas poucos estiveram focados no espaço intra-urbano. Em face dessa lacuna na literatura de Economia de Aglomeração, a análise nesta tese debruça-se sobre a Região Metropolitana de São Paulo (RMSP), que foi dividida em áreas homogêneas de 1 km2. Dois são os objetivos centrais desse trabalho. Primeiro, buscou-se identificar as áreas mais relevantes quanto à aglomeração de trabalhadores na RMSP, ou seja, os subcentros de emprego (SBD). Para tanto, utilizaram-se os microdados geocodificados do Ministério do Trabalho (RAIS- MTE) para os anos de 2002, 2008 e 2014. Uma nova abordagem empírica foi desenvolvida, utilizando Regressões Ponderadas Geograficamente e uma regra objetiva de valor de corte. Os resultados apontam para três SBD nos anos de 2002 e 2008. No ano de 2014, a abordagem metodológica desenvolvida nessa tese com valor de corte mais restrito identifica apenas dois SBD. Nos dois períodos iniciais, os SBD se localizam em Barueri, São Paulo e São Caetano do Sul. No último ano avalidado, localizam-se em Barueri e São Paulo. O padrão observado é que o emprego localizado nas áreas centrais de São Paulo apresenta nível de crescimento relativamente maior do que nas demais áreas. Os demais SBD perdem não apenas em termos de emprego, mas também em termos de área, isto é, as áreas dos SBD nesses municípios se reduzem. Em 2002, os SBD de Barueri e São Caetano do Sul ocupavam áreas de 5 e 7 km2, respectivamente. Em 2014, o primeiro ocupava 1 km2 e o segundo deixou de existir. Em São Paulo, a área se elevou de 79 km2 para 90 km2. Os resultados sugerem elevada concentração espacial do emprego na RMSP. No segundo ensaio, objetiva-se identificar o impacto da aglomeração sobre os salários dos trabalhadores e, adicionalmente, testa-se a hipótese de atenuação espacial da aglomeração. Para tanto, construiu-se uma base de dados longitudinal e considerou-se uma especificação com múltiplos efeitos fixos e defasagem espacial da aglomeração de emprego. Mesmo em face de uma especificação mais restritiva, os resultados sugerem efeito positivo da aglomeração, o qual é atenuado com o distanciamento espacial. Em outras palavras, a aglomeração impacta positivamente o salário. Em estimações que desconsideram a questão da endogeneidade, estima-se um efeito direto (na própria área) de 0,039%, efeito indireto de primeira ordem (em áreas contíguas) de -0,11% e efeito indireto de segunda ordem (anel externo às áreas contíguas) de -0,23%, normalizado por 100,000. Ao tratar o problema da endogeneidade, através do uso de variáveis instrumentais, obtém-se efeito direto de 1,78%, indireto de primeira ordem de -2,12% e o efeito de segunda ordem não é estatisticamente significante. / Agglomeration economies are externalities that impact on prices in the economy. The interactions that occur in agglomerations are relevant for the understanding of the benefits generated by proximity. These benefits directly affect workers\' wage, real estate prices, etc. Many papers have focused on non-market interaction in aggregated labor markets, but intra-urban labor markets have received less attention. Seeking to fulfill such lack, 1 km2 areas of the Metropolitan Area of São Paulo (MASP) are taken as the scope of analysis of this study. The central objectives of this dissertation are twofold. First, in chapter 3, I identified and characterized the most relevant areas in terms of job agglomeration in the MASP, named subcentral business districts (SBD). For this purpose, the geocoded matched employer-employee database of the Ministry of Labor (RAIS- TEM) was used. I developed a new empirical approach to identify the SBD, using Geographicaly Weight Regression and cut-off rules of identification. The results identified three SBD in the years of 2002 and 2008, and only two in 2014. Considering the two initial periods, the SBD are located in the municipalities of Barueri (SBD-BAR), São Paulo (SBD-SAO) and São Caetano do Sul (SBD-SCS). In the last year, the SBD are located in Barueri and São Paulo municipality only. The employment located in the central areas of São Paulo shows a relatively higher amount of employee than in the other SBD areas. SBD-BAR and SBD-SCS lost not only in terms of employment, but also in terms of area. In 2002, these last two SBD occupied areas of 5 and 7 km2 respectively. In 2014, the SBD-BAR occupied 1 km2, while the SBD-SCS is not ranked at all. In São Paulo, the area ranges from 79 km2 to 90 km2. The results stemmed from the first paper suggest a high spatial concentration of employment in the MASP. In the second paper (chapter 4), the objectives are to identify the impact of agglomeration on workers\' wages and test the agglomeration spatial attenuation hypothesis (SAH). For that, I use employer-employee RAIS database and consider a specification with multiple fixed effects and spatial lags of the employment agglomeration as a strategy to SAH identification. Even in the face of a more restrictive specification, the results suggest a positive effect of agglomeration, which is attenuated as the spatial distance increases. In other words, agglomeration affects positively workers\' wage in the workplace area. Estimates without solving for endogeneity between wage and agglomeration indicate a direct effect of 0.039% (in the area itself), a first-order indirect effect of -0.11% (in the contiguous areas), and a second-order effect of -0.23% (in the ring around the contiguous areas), normalized by 100,000. When considering instrumental variables, the estimated direct effect on wages becomes 1.78%, the first-order effect changes to -2.12%, and the second order effect is not statistically significant.

We set up a trade model with heterogeneous firms and a worker population that is heterogeneous in two dimensions: workers are either skilled or unskilled, and within each skill category there is a continuum of abilities. Workers with high abilities, both skilled and unskilled, are matched to firms with high productivities, and this leads to wage differentials within each skill category across firms. Self-selection of the most productive firms into exporting generates an exporter wage premium, and our framework with skilled and unskilled workers allows us to decompose this premium into its skill-specific components. We employ linked employer-employee data from Germany to structurally estimate the parameters of the model. Using these parameter estimates, we compute an average exporter wage premium of 5 percent. The decomposition by skill turns out to be quantitatively highly relevant, with exporting firms paying no wage premium at all to their unskilled workers, while the premium for skilled workers is 12 percent.

Using cross-sectional and longitudinal data from EU-SILC for the Czech Republic this thesis shows that mothers suffer wage penalty, whereas fathers gain wage premium. These results are in accordance with literature abroad. This thesis also shows that parenthood has greater impact on individuals with higher education, that motherhood penalty is lower for single mothers, whereas fatherhood premium is higher for single fathers, and that there is stronger self-selection of mothers into specific jobs than in case of fathers. Model of fixed effects suggests that parenthood is connected with unobservable characteristics that have positive effect on parent's wages. Results of this thesis are in accordance with human capital theory, division of labor within the household, self-selection of mothers into more mother-friendly jobs. But results concerning lower work effort of mothers are inconclusive.

La acumulación de Capital Humano es fundamental para explicar recientes procesos de crecimiento económico experimentados en numerosos países, los cambios en la distribución de la renta salarial, en la localización de la actividad productiva, del comercio, etc... Por ello, consideramos fundamental avanzar en el conocimiento que dicha acumulación haya podido tener en una economía como la española, caracterizada recientemente por un crecimiento intenso en la educación de los trabajadores. Por este motivo se realizan tres análisis. En el primero, descomponemos la distribución de los salarios para conocer qué factores han afectado a su cambio desde 1980. Dedicamos especial atención al efecto que el cambio educativo haya podido tener en la desigualdad salarial. En un segundo análisis descomponemos el cambio en la brecha salarial entre trabajo cualificado y no cualificado entre cambios en la demanda y oferta de cualificación. Por último, estimamos las externalidades del capital humano en España a nivel regional. / Human Capital accumulation is crucial for explaining countries' recent economic growth episodes, changes in income and wage distribution, production localization, trade, etc. Thus, we consider important enhance the knowledge for the Human Capital accumulation effects on Spanish economy, characterized by intensive growth of educated workers. Then, we do three analysis. First, we decompose the wage distribution to know which factors are behind its changes since 1980. We give special attention to education effects on that wage inequality change. In our second analysis, we decompose the more educated wage premium change between changes in demand and supply of skills. Finally, our third analysis try to estimate human capital externalities for Spanish regions.

Cette thèse explore la dimension géographique des disparités entre les sexes dans le marché du travail. Les questions étudiées incluent la variation de la prime salariale urbaine entre les sexes (chapitre deux), l'exploration des différents mécanismes derrière les effets importants de la localisation géographique sur les gains du marché du travail des femmes (chapitre trois), et de l'écart entre les sexes sur les rendements d'expérience urbains (chapitre quatre). Le deuxième chapitre entreprend une analyse transversale à l'aide de données françaises pour estimer la prime salariale urbaine et sa variation entre les sexes. Les résultats confirment l'existence d'une prime salariale urbaine nettement supérieure pour les femmes. Un doublement de la densité de l'emploi dans une zone donnée entraîne une réduction de 2,4 pourcent de l'écart salarial entre les sexes, une valeur qui augmente de 4 pourcent lorsqu'on exclut la catégorie professionnelle des ouvriers. Contrairement au reste des professions, l'effet de la densité favorise les hommes dans la catégorie des ouvriers. Le troisième chapitre cherche à trouver les mécanismes à l'origine de l'effet importante de la localisation géographique sur les gains du marché du travail pour les femmes en employant l'approche par l'estimateur « within ». Les résultats suggèrent que la moitié de la prime salariale urbaine est attribuée sur la base d'un tri des travailleurs selon le type de compétences à travers des différentes zones. Cependant, en complément du tri de compétences, d'autres hétérogénéités individuelles contribuent également à l'excès de la prime salariale urbaine pour les femmes. / This dissertation explores the geographical dimension of the gender gaps in the labor market. The investigated issues include the variation of urban wage premium across genders (chapter two), exploration of different mechanisms behind stronger location effects for females' labor market gains (chapter three), and the gender gap in the urban returns to experience (chapter four). The second chapter undertakes a cross-sectional analysis by using French data to estimate the urban wage premium and its variation across genders. The findings confirm the existence of an urban wage premium that is significantly higher for women. A twofold increase in employment density of an area results in a 2.4 percent reduction in the gender wage gap, which increases to 4 percent when we exclude manual workers occupational category. Contrary to the rest of the occupations, the density effect favors men in the manual workers category. The third chapter seeks to find the mechanisms behind the stronger location effects on labor market gains for women by employing the within estimate approach. Results suggest that half of the urban wage premium is contributed by the sorting of workers according to skill type across different areas. However, in addition to skill sorting other individual heterogeneities also contribute to the excess urban wage premium for females. Firm level agglomeration effects attribute a minor part to the excess urban wage premium for females. The left over premium is a result of pure urban effects (lower discrimination, better matching, urban amenities).
